Abstract

AbstrakPermasalahan dalam riset ini merupakan rendahnya hasil ulangan harian siswa yang disebabkan oleh rendahnya keterampilan representasi matematis siswa. Riset ini ialah riset deskriptif dengan memanfaatkan instrumen berbentuk soal uji yang berupa soal penjelasan serta pedoman wawancara. subjek penelitian berjumlah 23 orang siswa, penerapan pembelajaran di lakukan secara daring di masa pandemi Covid-19. Instrumen riset di bagikan melalui whatsapp grup, serta wawancara dicoba lewat via telpon. Informasi yang diperoleh dianalisis buat mengenali keahlian representasi matematis siswa. Menurut hasil analisis lembar jawaban serta wawancara dari 23 siswa diperoleh kesimpulan jika ketercapain siswa pada indikator representasi visual 65,2%; indikator representasi ekspresi maupun persamaan 43,5%; dan indikator representasi kata-kata 41,2%. Hal ini menunjukkan bahwa kemampuan representasi matematis siswa masih perlu diperhatikan untuk dapat ditingkatkan.  AbstractThe problem in this research is the low results of students' daily tests caused by the low mathematical representation skills of students. This research is descriptive research using an instrument in the form of test questions in the form of explanatory questions and interview guidelines. The research subjects were 23 students, the application of learning was carried out online during the Covid-19 pandemic. The research instrument was distributed via WhatsApp group, and interviews were tried via telephone. The information obtained was analyzed to identify students' mathematical representation skills. According to the results of the analysis of the answer sheets and interviews of 23 students, it was concluded that the student's achievement in the visual representation indicator was 65.2%; representation indicators of expressions and equations 43.5%; and indicators of representation of words 41.2%. This shows that the mathematical representation ability of students still needs to be considered so that it can be improved.

Abstract

This study aims to evaluate the effectiveness of FlipaClip as a learning media, and to compare the problem-solving abilities of students who learn using FlipaClip and PowerPoint. This study employed the ADDIE development paradigm (Analysis, Design, Development, Implementation, and Evaluate) as a framework for research and development (R&D). The findings demonstrated the validity and viability of learning media that use a contextual approach to linear program content. With extremely valid criteria, the material validation findings came out at 84.38%. The validation results from media experts were 94.79%, which is considered highly valid. Although the student response received an assessment percentage of 83.64%, the response also met the FlipaClip-based learning media's "very interesting" requirements, indicating that it is practical to use. Moreover, the research shows that FlipaClip-based learning media on program material can improve the mathematical problem-solving ability of class XI students. Quantitatively, the difference is shown by the interpretation of N-Gain obtained in the experimental class, which is quite an effective category with a percentage of 70.22%. The average mathematical problem-solving ability of grade XI students who are given FlipaClip-based learning media is higher than the average student who is not given the media, as indicated by the results of the independent sample t-test, namely the Sig. (2- tailed) value of 0.000 <0.05.

Abstract

Critical thinking and political literacy are essential competencies in 21st-century education; however, they are often developed separately in school learning. This study investigates the relationship between mathematical critical thinking ability and students’ political literacy at the senior high school level. Using a quantitative correlational design, data were collected from 80 eleventh-grade students selected through stratified random sampling from three public high schools in Yogyakarta City. The instruments consisted of a mathematical critical thinking test and a political literacy questionnaire, both of which demonstrated acceptable validity and reliability. Data were analyzed using the Pearson Product–Moment correlation. The results revealed a significant positive correlation between mathematical critical thinking and political literacy (r = 0.58, p < 0.01), indicating that students with stronger mathematical reasoning tend to exhibit higher political literacy, including a better understanding of democratic values and more rational civic attitudes. These findings demonstrate that mathematical critical thinking contributes meaningfully to students’ political literacy. The study highlights the importance of integrating socio-political contexts into mathematics instruction as an interdisciplinary approach to fostering analytical and responsible citizenship in a democratic society.

Abstract

Kemampuan pemecahan masalah geometri menuntut ketelitian, keterampilan berpikir logis, dan reflektif. Namun, banyak siswa di jenjang Sekolah Menengah Pertama (SMP) memiliki gaya kognitif impulsif, yaitu kecenderungan menjawab dengan cepat tanpa analisis mendalam sehingga sering melakukan kesalahan konseptual maupun prosedural. Kegiatan pengabdian ini bertujuan untuk meningkatkan kemampuan pemecahan masalah geometri siswa impulsif melalui program pendampingan belajar berbasis reflektif. Kegiatan dilaksanakan di salah satu SMP mitra dengan melibatkan 15 siswa kelas VIII yang diidentifikasi memiliki gaya kognitif impulsif menggunakan instrumen Matching Familiar Figures Test (MFFT). Metode pelaksanaan meliputi empat tahap, yaitu: (1) identifikasi karakteristik siswa impulsif, (2) pelatihan berpikir reflektif dan strategi penyelesaian masalah geometri, (3) pendampingan belajar kelompok kecil menggunakan lembar refleksi berpikir berbasis langkah Polya, serta (4) evaluasi hasil dan refleksi bersama. Hasil kegiatan menunjukkan adanya peningkatan kemampuan siswa dalam memahami masalah, menyusun strategi, serta memeriksa kembali langkah penyelesaian. Selain itu, siswa mulai menunjukkan perubahan perilaku belajar yang lebih hati-hati dan sistematis. Guru mitra juga memperoleh pemahaman baru mengenai pendekatan pembelajaran reflektif yang sesuai dengan karakteristik siswa impulsif. Dengan demikian, pendampingan reflektif terbukti efektif membantu siswa impulsif mengembangkan kemampuan pemecahan masalah geometri secara lebih terarah dan mendalam.

Abstract

The study aimed to determine the effect of participating in the exact student association organization (HIMEKS) and the intensity of learning on student achievement in mathematics education at FKIP-UMPRI. The activity in question was the involvement and an essential role in the organization's activities to foster and develop talents and increase student motivation. The intensity of learning included motivation, time or duration, discipline, concentration, frequency, activity, and presentation. This type of research used ex post facto with a quantitative approach. The population was all students of mathematics education FKIP-UMPRI. The research sample was Himeks administrators who were taken using a purposive sampling technique, totaling 43 people. Data collection through the distribution of questionnaires and documentation. The data analysis technique used simple regression analysis technique and multiple regression analysis. The results of data analysis: (1) there was an effect of activities following the HIMEKS organization with a contribution of 9.1% on student learning achievement. A positive effect with a correlation coefficient (r_x1y) of 0.302 with a low category; (2) there was an effect of learning intensity on student achievement with a contribution of 28.7%. The positive effect showed by the correlation coefficient (r_x2y) of 0.536, including the medium category; (3) there was an effect of participating in the HIMEKS organization and the intensity of learning together on student learning achievement 32.0%. A positive effect with a correlation coefficient of r_x1x2y=0.566 in the medium category.
